Hello, I think I figured it out: one mohr's circle is plotted with x being normal strain and y being shear strain, and the other plot is the one I am used to: the shear stress on the y-axis and normal stress on the x-axis. So now all the equations make sense to me.Chestermiller said:What are your equations for the normal strain and shear strain on a specified plane, given the principal strains in the x and y directions
Mohr's Circle is a graphical method used in mechanics to visualize and analyze stresses and strains on a material. It was developed by German engineer Christian Otto Mohr in the 19th century.
Mohr's Circle represents strain as the radius of a circle. The center of the circle represents the average strain, while the radius represents the difference between the maximum and minimum strains.
The y-axis on Mohr's Circle represents the maximum strain. This means that the maximum strain will be located on the circumference of the circle at the point where the circle intersects with the y-axis.
Mohr's Circle can be used to determine the principal stresses and strains by finding the point on the circumference of the circle that is farthest from the center. The coordinates of this point will represent the principal stresses and strains.
While Mohr's Circle is a useful tool for visualizing and analyzing stresses and strains, it is limited to two-dimensional problems and does not take into account the effects of shear stress. It is also important to note that Mohr's Circle assumes linear elastic behavior and may not accurately represent the behavior of non-linear materials.
